笔者曾多次遇到这样的情况;即SL-E514联合收割机在正常收割条件下,各工作部件运转正常,按照说明书提供的数据反复调整滚筒转速、凹板间隙及其他工作部件,并经过反复试验,但是不管如何调整,收割作业时,不是粮食抛撒损失过多,就是籽粒破碎率太大或粮仓杂草过多。后来发现是发动机在带负荷工作时,转速降到了额定转速(2000转/分)以下。经检查发现,原因是发动机供油拉杆限位
I have repeatedly encountered such a situation; that is, SL-E514 combine harvester in normal harvest conditions, the working parts of the normal operation, according to the instructions provided by the data repeatedly adjust the cylinder speed, concave plate gap and other working parts, and after repeated However, no matter how the adjustment is made, the loss of grain is not excessive when the harvesting operation is carried out, that is, the grain crushing rate is too high or the grain storage weed is too much. It was later found that the engine is working with a load, the speed dropped to the rated speed (2000 rev / min) below. The inspection found that the reason is that engine oil rod limit
